STEPHEN J. MEEKER, OF NEWARK, lNEW JERSEY, ASSIGNOR TO HIMSELF AND DAVIDM. MEEKER, OF SAME PLACE.

IMPRCVEMENT IN CAST-IRON WINDOW-SASH-ES.

Specification forming part of Letters Patent No. 15 l, 897, dated June9, 1874 application liled March 11, 1874.

To all whom it may concern:

Be it `known that I, STEPHEN JONES MEEKER, of Newark, in the county ofEssex and in the State of New Jersey, have invented certain new anduseful Improvements in Cast-Iron Window-Sashes and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, forming a part of thisspecification.

Figure l is an elevation, the outer or mainV frame being of wood. Fig. 2is a vertical section ofthe same. Fig. 3 is a vert-ical section, showingthe entire sash of iron. Fig. 4 is an velevation of a horizontalmullion. Fig. 5 is a cross-section ofthe saine. Fig. 6 is acrosss'ection of the cast-iron Inain frame.

My invention relates to the construction of window-sashes out ofmalleable cast-iron 5 and consists in making it in several parts, one ofwhich is a hollow cross-niullion, secured together by horizontal boltsand by rivets.

Heretofore rolled iron has generally been used for iron sashes forEre-proof buildings, jails, orl asylums. The cost of' iron in this form,in consequence of labor, is so high as to restrict its use.

In my invention I use malleable cast-iron, casting the several portionsof the frame, such as the meeting-rail, side and bottom strips, andhorizontal and vertical division-strips or mullions, in separate pieces,so that they may be readily cast and tempered or annealed.

The main frame A may be made either of iron or wood. When made of Wood,as shown in Figs. 1 and 2, the four pieces A, which f compose it, areput together in the usual way,

and secured at the corners. rlhe outer molding-strips B are each cast inone piece, and made malleable, and fitted and riveted together at theircorners, as shown at X. The

vertical division-strips or Inullions C are also cast separately,annealed, and :fitted in place between the top and bottom rails, towhich they *are secured by rivets, as at Y. The horizontaldivision-strips or mullions D are cast, made malleable, and tted in asimilar manner, but are of short lengths-only the Width of each panedandare cored out so as to be hollow for an iron bolt to pass through, andby means of a screw-nut to clamp the parts together. E is an iron boltpassing through the side strips B and mullions D. A nut, a, on end ofthis bolt serves to clamp the parts together. The various parts, B C DE, thus riveted and screw-bolted together, are then placed within thewindow-frame A, and secured thereto by screws Z.- The sash is then readyfor the glass.

When the main frame A is made of iron, (common gray iron will answer agood purpose,) it is cast in four pieces, having a 1 1 cross-section,and riveted at the corners, as shown in Fig. 6, having the inner edgecast with a molding or in Inullion form, as shown at m in said figure.The strips C are then put in place and riveted. The strips or lnullionsD are then putin place, and the bolt E passed through them, and throughstrips C and framestrips A, and drawn up tight by nuts Z. The sash isthen ready to be glazed.

What I claim as new, and desire to secure by Letters Patent, is-

1. The hollow cross-mullions D, in combination With bolt E, whenconstructed Vand operating substantially in the manner and for thepurposes set forth.

2. The combination of the parts B C D with frame A by means of bolt Eand rivets, sub stantially as and for the purposes set forth.

In testimony thatI claim the above-described invention I have hereuntosigned myname this 21st day of February, 187 4.

STEPHEN J. MEEKER.
